finescenery.com Posted February 22, 2013 Share Posted February 22, 2013 <p>Hello everyone,</p><p>I've been with photo.net for quite a while, although not posted many photos. You can check some at my website in the profile but this is not my point. One day I decided that I'll be more helpful to community not by making more landscapes but helping others learn something that I've learned about photography.</p><p>So my LensTutorial project was born, you can check it here: <a href="http://www.lenstutorial.com">www.lenstutorial.com</a><br>It was inspired by many dof calcs that only give you dull numbers. As opposite to that I tried to visually represent such interrelated concepts as focal length, field of view, dof and subject distance on one picture and make it all interactive. You can roll the dials the way you like and learn how they work.<br>Presently there is only version for iPhones/iPads which is free.<br>Suggestions and feature requests are welcome.<br>But ultimately I only seek a thumbs up. Please check it out and share your thoughts.</p><p>Cheers, Denis</p> Link to comment Share on other sites More sharing options...
Jeff Lear Posted February 22, 2013 Share Posted February 22, 2013 <p>I didn't go through all of the tutorials but I've gotta say, that's a pretty cool looking (and useful) app. Nice work.</p> Link to comment Share on other sites More sharing options...
m_tt_donuts Posted February 22, 2013 Share Posted February 22, 2013 <p>A suggestion for the focal length section, new photographers have a hard time understanding the effects of focal length. They have a 18-55mm kit lens and want a new lens but have no idea what 200mm means as it relates to what they have. I recommend letting them realize if they take 50mm, cut it into quarters, one of those quarters will be 100mm. Cut that view again into quarters that will be the view of a 200mm, rinse and repeat there's diminishing returns. It helps prevent the shock when they get a 70-300mm and wonder why the difference between 265mm and 300mm is almost nothing but the difference of their kit lens between 18mm and 55mm is massive... when they're both about 35mm. </p> <p>Nice work. Like the format and imagery. Thumbs up for me! </p> Link to comment Share on other sites More sharing options...

finescenery.com Posted February 24, 2013 Author Share Posted February 24, 2013 <p>Dear all,<br> Thanks for comments and suggestions.<br> @Tim,<br> Sorry for contradiction. I wanted to convey that I'm happy to learn that someone finds this useful, but if people are willing to spare their time to write about missing functionality they want it is even better.</p> Link to comment Share on other sites More sharing options...
